I was updateing my psp and i turned it off and now it wont come back on the green light will come on. but it will just shut off.

First you have to take out the battery and use charger to turned on and when it turn on just put on the battery or take out the battery and wait for minutes then put it on and tur on,if that doesn't work when you turn on just hold R and start or repair it

your psp is bricked, this usually occurs when your psp shuts off during an update, or you tried to install custom firmware and failed.

your only hope is to get it repaired, or use to use a pandora's battery and try to recover it yourself.

firmware could have crashed. welcome to a 150$ paper weight. sorry.

computers can run into the same issue if a bios update fails or corrupts.

sony might be willing to fix it.. maby.. or game stop might buy it off of you.

Put psp to charge when turning on

green light comes on but the screen wont, i was on updating the psp and accidently turned it off and now it wont come on.

this is a common problem with psp`s you have what they called "bricked" your psp you can have it unbricked by some one with a pandora battery and a memory card.

the firmware is busted, which kills the system. i dont know how to fix it manually, but sony will fix it for a fee unless you find the warranty

Is the green light on? if the light is on, your psp is bricked. Create a pandora battery and a memory card to unbricked your device. Search google for creating a pandora and the memory card.

SOMETIMES TAKE THE BATTARY OUT AND PUTTING BACK IN AGAIN WORKS.

What happened was that the new game was doing the update before you said no. It was removing the memory from the psp and when you try to turn it back on, there is no memory for it to start. The only that can be done is that it has to going into the shop for repair/exchange....there is nothing you can do to get back the psp working again. It also happened to me and Sony explained the problem.
